Cell type composition in bulk prostate cancer tissue is a prognostic biomarker.

ABSTRACT: Prostate cancer, among the most prevalent cancer types globally, exhibits marked heterogeneity and varying disease progression and clinical outcomes. Improved molecular subtyping is needed for patient stratification. Since prostate cancer has relatively few somatic point mutations, whole-transcriptome data instead offers a rich and relevant source of molecular data. We analyzed bulk tissue transcriptomes from four cohorts to characterize primary prostate cancer's cell type composition. A deconvolution of cell types was performed based on gene expression profiles. Patients with available multi-sample regional data from different tumor foci were analyzed for intrapatient heterogeneity. Three cell type composition subtypes were defined: T cells enriched (TCE), epithelial cells enriched (EPCE)
